LAB REPORT WASTEWATER TREATMENT PROCESS 2
Lab Report 1 Water Treatment Process
Background
Water treatment is an essential process. It is, therefore, a process which is
unquestionable, and this is primarily in the modern world which is made up of a variety of
unnatural bacteria and pollutants which have occupied the water reserves and supplies
(Elmorsi et al.2010). The process helps to ensure that harmful substances are eliminated and
hence making water clean and safe for consumption in residential commercial and industrial
areas. It, however, puts a lot of concentration on the removal of harmful substances which are
non-consumable such as deadly microbes, chemicals, and sediment particles.
Objective
The primary objective of the experiment is to enable carious students to comprehend
the water treatment process especially the standard rudiments part of the process. It will
typically concentrate on various elements as follows
i. Measurement of the purified and raw water
ii. Measurement and comprehension of the effects of chlorine specifically during the
disinfection as a result of product formation.
iii. Measuring of chlorine decay and preparation of a variety of ferric chloride doses
iv. Influencing of the chemical and physical treatment processes
Report Structure
The structure of the report will entail the use of procedural outlines of the experiment,
the findings, a discussion which will encompass identification of any errors and possible
solutions and then it will finalize with a conclusive paragraph.
Procedure
i. The first procedure will involve checking for UV254, DOC, Turbidity, and Color of
water sample provided.

ii. The water sample is then placed in sedimentation which consists of suspended solids
for thirty minutes.
iii. The next step will involve testing of UV254, Turbidity, DOC and Color and the
results compared with the past findings which were obtained before sedimentation
iv. After the above step, fine particles will be added to the Ferric Chloride (FeCl3).
v. A jar test is then carried out using a mixing speed of 200rpm for about 3 minutes and
later put control for thirty minutes at 30 rpm(Igunnu, & Chen, 2012).
vi. The next step involves leaving the sample kept together until all the flocs have settled
and this is after the coagulation.
vii. Using a prewashed 0.45μm CA filter, filter the water and experiment with the three
parameters of the filtrate.
viii. Add 0.2mg/L of chlorine and inspect the chlorine decay.
ix. Using Gas Chromatography (GC), measure Trihalomethane (THM)
Discussion
From the findings of the experiment, due to poor time management and other limitations in
the laboratory, the original investigation was not carried to completion. However, the water
quality evaluation was only tested up to the pre-filtration process and thus leaving the post
sedimentation process (Wang et al. 2010). 29.5 turbidity colour rating, 1.8969 rating of UV
and 8.976 level of DOC were displayed in the original sample. Also, there was no
comparison of the various parameters of water, and the third step of the experiment was not
carried out. Based on the results as mentioned above, the overall conclusion of the report may
have been affected. Unfortunately, it is believed that the said values were lowered by the
filtration process(Yin, 2010). It was, therefore, necessary for the testing of optimum ferric
chloride at 10, 15, 25 and 50 mg/L in the second part of the experiment. The sample which
was obtained influenced the values of turbidity leading to an indecisive interchange of values,
